中文摘要: 提出了一种基于数字全息术的用于版权保护的水印方法.首先将含有版权保护信息的图像生成数字全息图,然后通过小波变换将其作为水印嵌入要保护的对象,对提取的水印进行数值重构可以得到版权保护信息.由于全息图具有不可撕毁的特性,所以该方法对各种攻击具有较强的抵御性.测试结果证明,该方法的鲁棒性较好.
Abstract:A new method to protect the copyright based on digital holography is proposed.The Fresnel hologram of copyright image is embedded in the object to be protected through discrete wavelet transform (DWT).After the watermark detection, the copyright information appears in the reconstruction of hologram.With the higher redundancy feature in the hologram, the proposed technique could actually survive several kinds of image processing.A series of experiments are carried out in image protection and the results prove that the presented method has good robustness.
